THRESHING AND SEPARATING DEVICE OF A COMBINE HARVESTER Russian patent published in 2021 - IPC A01D41/12 A01F12/18 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to agricultural engineering, in particular to threshing and separating devices of combine harvesters. The device contains a frame, a threshing drum, sub-drums installed under the working bodies, and a distributor beater. The device is equipped with two rotors, pivotally mounted in the frame on one side on a roller bearing, and on the other side on the gearbox shaft. The rotors consist of threshing and separating elements. The rotors are located transversely to the longitudinal axis of the combine and rotate in opposite directions relative to each other. Whips are used as threshing elements, and blades are used as separating elements. The length of the threshing zone with whips is one-fourth of the total length of the rotor. The threshing and separating zones interact with the sub-drums installed under the rotors.

EFFECT: use of the invention will increase the productivity of the combine harvester, reduce the load on the threshing and separating device, as well as reduce the grain shattering and damaging.
